I Patented 21, 1930 UNITED STA res JOHN GREEN, OAKLAND, CALIFORNIA FRAMEconsraucrron Application. filed May 14,

My invention relates to improvements in frame constructions,particularly useful in the erection of the structures commonly known assteel buildings, although also useful for other purposes, including thebuildtion andthereby effecting a substantial saving in labor cost, butalso eliminating the noises made by the workmen in securing the rivets(which noises have lately been found decidedly objectionableparticularly in the larger cities throughout the country), as well asmaterially shortening the time during which portions of the adjacentside-walls and streets must-be set aside for the use'of the contractorerecting the building.

With the foregoing and other objects and purposes in view which willappear as the description proceeds, my invention resides in thecombination and arrangement of parts and in the details of constructionhereinafter described and claimed, it being understood that changes inthe precise embodiment of the invention herein disclosed can be madewithin the scope of what is claimed without departing from the spirit ofthe invention.

Referring to the drawings in detail, throughout which like referencecharacters designate like parts:

1 'The numerals 1 and 2 designate the vertically extending columns andhorizontally extending girders, respectively, of the present invention.j

The columns, which are preferably formed of structional steel either ofthe usual I-beam or 2-piece channel-steel stock, have their .lower endsdisposed upon and secured, in any preferred manner, to a suitablefoundation 3, formed preferably of concrete.

In the event that any of the columns 1 are found to be too short for thepurpose intended, they maybe extended to any suitable length bydisposing two or more together endto-end, in which position the tworegistering ends are maintained in fixed longitudinal alignment by meansof a rectangular. annular binding sleeve 4 fitted snugly around againstthe two abutting end portions of the columns,

extending about equidistant from the abut-' ting end of each (see Figs.1 and 3).

Intermediate the ends of the columns 1 are rigidly secured supportingbrackets 5. These supporting brackets, which comprise, each, a verticalmember 5, preferably riveted. or welded to the sides of the columns 1,and a horizontally extending member 5 projecting at right anglesoutwardly from the upper end of said vertical member. In the presentillustrated form of the invention the supporting brackets 5 are securedby means of rivets 6, which pass through both the lower members 5 of thebrackets and the body portions of the-columns 1.

' Encircling the column limmediately above the bracket 5, and preferablyseating on the latter, is a rectangular annular securing band 7,. whichis adapted to fit snugly, butnormally operatively slidably, against thesides of the column, excepting, however, the side of the column againstwhich is secured the supporting bracket 5. On this side itris spaced 2.suitable distance outwardly fromt e column to form a slot 7 the functionof which will become apparent as the description proceeds. v

Longitudinally across the length of the girders 2, are secured securingplates 8 by means of rivets 9. These securing plates are somewhat longerthan the girders to which they are secured, to permit their ends beingstruck at right angles downwardly to form locking lips 10, which arespaced suitable distances outwardly from the squared ends of thegirders, to form interlocking niches 10 between the ends of the girdersand said locking lips.

The ends of the girders 2 are disposed on their respective brackets,previously attached to the columns, and are permanently secured to saidcolumns by slipping the locking lips 10 down into their'respective slots7 a as far as they can go, and disposing the adjacent sides of thesecuring bands 7 in the niches 10 The dimensions of the interassociatingparts of the locking lips 10, securing bands 7, relative to the slots 7a and niches 10*, should be such that when these parts are disposed intheir proper positions for permanently bindin the girders to thecolumns, the girders wi I bear firmly on their respective supportingbrackets 5, and there will besubstantially no longitudinal movement ofthe girders relative to the columns.

The'securing plates9 are referably secured to the girders 2, and thesupporting brackets ,5 to the columns 1, 'at the shops or mills wherethe steel isprepared and before the same is delivered to the premiseswhere the frame is to be erected. a

Where two or more girders are disposed in the same horizontal plane andhave ends attached to the same column but on different sides thereof,obviously, there must be secured a'supporting bracket 5 for each girder,and the securing band 7 will have to be made large enough relative tothe transverse dimensions of the column to allow suflicient room betweenthe latter and said band to permit the'entrance therebetween of thelocking lips 10 of each girder (see Figs. 5, 6 and 12). In the event oftwo or more girders being secured to .the same column, as above stated,it will be found that thiswill result in rectangular vertical extendingopenings 11 being formed at the inner corners of the supporting bands atthe intersections of the adjacent edges of the locking lips of each pairof girders disposed at relative right angles.

These openings are preferably filled by driving closely fitted lockingpins 12 thereinto (see Fig. 12).

The columns 1 may comprise a single length of steel, or, if preferred,as would likely be the case in the erection of tall structures, two

or more columns may be butted together end-to-end, and held inlongitudinal alignment by encircling the connected end portions of eachpair of abutting columns with an annular rectangular sleeve 4. If saidpairs of abutting columns are of unequal transverse dimensions, as wouldbethe case if a smaller column was set on top of a larger one, thesleeve 4 should be made with unequal lnterior dimensions correspondingwith the different dimensions of the columns, so as to fit snuglyagainstthe sides of each.

Having described my invention, what I claim and desire to secure byLetters Patent, is: I

1. In a frame construction of the character between the outer face ofthecolumn and the inner face of the band.

2. In a frame construction of the character described, the combinationwith a vertically extending column having a supporting bracket securedto and extending laterally outwardbeyond one side thereof, of a girderhaving an end portion bearing on and supported by said bracket, a lipcarried by said girder, a band slidably encircling said column andembracing said lip.

3. In a frame construction of the character described, the combinationwith a vertically extending column, of a locking band encircling saidcolumn, a horizontally extending girder, a locking lip at one end ofsaid girder extending across the end thereof in spaced relation theretoand disposed between a portion of said band and said column, and meanscarried by the column for supporting the girder.

described, the combination with a column 4. In a frame construction ofthe character set forth, the combination with a vertically extendingcolumn having a su porting bracket on one side, of a securing andencircling said column above said bracket, 8. horizontally extendinggirder having one end portion resting upon and supported by saidbracket, a securing plate fixedly secured to said girderand having alocking lip overhangmg one end of said girder and in spaced relationthereto, said locking band having a portion disposed between saidlocking ip and girder whereby one end of said girder 1s I heldsubstantially in fixed relation to said column.

5. In a frame construction of the character set forth, a horizontallyextending girder, and a securing plate extending longitudinally of saidgirder and fixedly secured to the upper side thereof, a free end portionof said plate extending downwardly across and in spaced'relation to anend of the girder to form a locking lip adapted to interlock andcooperate with means carried by a column to secure the girder to thecolumn.

6. In a frame construction of the character described, a column, asupporting bracket secured to said column, a girder restin at one endupon said bracket, a lip carrie by said girder, and a band encirclingthe column and embracing said lip, all portions of said girder beingisposed intermediate the ends of the column.

In testimony of the foregoing being my own, I have hereunto atfixed mysignature this 30th day of April, 1929.

JOHN GREEN.
